A 15A line is wired with 14Ga wire as per electrical code ,on the other hand a 20A is done with 12Ga.Swapping receptacles is not a good idea,I think.If the current draw exceeds the maximum allowed by a 15A line.However I am not an electrician.Why don't run another dedicated 20A line?and be done with it.While I was renovating I run 6 new 20A lines to my listening room plus the existing but shared 2 20A and 2 15A .
Best of luck
